APPARATUS FOR OPTICAL COUPLING AND SYSTEM FOR COMMUNICATION: abstract simplified (18334386)

• This abstract for appeared for patent application number 18334386 Titled 'APPARATUS FOR OPTICAL COUPLING AND SYSTEM FOR COMMUNICATION'

Simplified Explanation

The abstract describes a new type of apparatus for optical coupling and a communication system. The apparatus includes a substrate and a grating coupler, which is placed on the substrate. The grating coupler consists of multiple coupling gratings arranged in a specific direction. These gratings have gradually decreasing refractive indices along that direction.

Original Abstract Submitted

Disclosed are apparatuses for optical coupling and a system for communication. In one embodiment, an apparatus for optical coupling including a substrate and a grating coupler is disclosed. The grating coupler is disposed on the substrate and includes a plurality of coupling gratings arranged along a first direction, wherein effective refractive indices of the plurality of coupling gratings gradually decrease along the first direction.
